Readers’ wildlife photos

May 29, 2018 • 7:30 am

Today reader Robert Seidel takes us on a tour of Kew Botanic Gardens. (I must confess that although I’ve been to London many times, I’ve never visited Kew). Robert’s notes are indented:

I’d like to offer you another travelogue to one of Britain’s biological pilgrimage sites: The Royal Botanical Gardens in Kew, London. A UNESCO World Heritage site, these splendid parks have been nationalized since 1840, but the project of a botanical garden goes back a further hundred years to a former princess of Wales, Augusta of Saxe-Gotha (1719-1772). On to the photos:
Palm house, built 1844-1848. Surely one of the most elegant buildings I have ever seen. Like the temperate house in the next pictures, it was a collaboration between architect Decimus Burton and industrialist Richard Turner, and according to Wikipedia, “the first large-scale structural use of wrought iron”.
Temperate house, built 1859-1863. By chance I not only chose a beautiful spring day for my visit, but also the day when this house was re-opened after five years of renovation. So it was quite busy, as seen on the next picture.
Temperate house, view from the balcony.
Kew Gardens is a major player in plant conservation, and one of the remarkable things about the temperate house is that you get to literally brush elbows with some critically endangered plants, which you’d think any sane person would keep under glass or in a secured building closed to public (I strongly suspect though there are backups in such places). This picture is of the St Helena Redwood (Trochetiopsis erythroxylon; by the way, whoever came up with that name must have had a sadistic streak!) As the nearby sign informs, this species is extinct in the wild, with all cultivars descended from a single tree which survived logging because it was too crooked to be used for timber. Apparently dwarfism now persists in the descendants, while originally the species grew to 8 meters tall, with straight trunks.
Not all conservation efforts are successful. This pot is a tombstone for another St Helena Plant, the St Helena Olive (Nesiota elliptica – not related to true olives). The last tree in the wild died in 1994, and self-incompatibility and low success rate of cuttings largely thwarted cultivation attempts, the last specimen succumbing to fungal infection in 2003.
 Tucked away in a corner behind the Princess of Wales conservatory (named after Augusta, not Diana, though it was opened by the latter) is the bonsai house, with some very old and magnificent (and valuable) exemplars. Unlike for all the critically endangered stuff, there is an alarm for these.
Eastern grey squirrel (Sciurus carolinensis). Cute though they be, let’s not forget that in Europe this is an invasive species, which has already displaced the native (and in my opinion even cuter) red squirrel in mainland Britain and may do the same in Ireland and possibly mainland Europe.
While I’m no biologist and have the highest respect for the scientists at Kew, this information struck me as odd – is there truly a relation between length of genome and reproduction rate? [JAC: readers?]

Tuesday: Hili dialogue

May 29, 2018 • 6:30 am

Today we have what the Brits would call a “bumper issue” of Hili, with extra stuff.

It’s back to work in the U.S.; the three-day Memorial Day weekend is over, and it’s Tuesday, May 29, 2018: National Biscuit Day. We’re not referring to the British “biscuit” (what Americans call “cookies”), but these luscious Southern breadstuffs, which are fantastic. I don’t think any other country has the equivalent:

And if you eat too many (best served with red-eye gravy and sausage), you can participate in another one of today’s celebrations: World Digestive Health Day.

First, an update on The Donald’s self-aggrandizing Memorial Day tweet, which I posted yesterday:

This is a response, not really from a WWII veteran, but from a journalist.

Today’s Google Doodle is an animation and game honoring the Danish biochemist S. P. L.S. P .L. Sørensen (1868-1939), who invented the pH scale for measuring acidity—the concentration of free hydrogen ions. The scale ranges from 0, very acidic, to 14, very basic. (The pH of Coca Cola, by the way, is 2.5, which is very acidic!). Your job in the game is to look at the six displayed food items and click on the arrows that put them either on the acidic side (left) or basic side (right). It’s not too hard!  I’m not sure why they’re doing this on May 29, which isn’t Sørensen’s birth or death dates, nor anything I can find connected with the invention of the pH scale.

On May 29, 1453, Sultan Mehmed II Fatih’s army captured Constantinople after 53 days of siege, finally ending the Byzantine Empire. And speaking of Coca Cola (or “Co-Cola” as they sometimes say in the South), it was on this day in 1886 that druggist John Pemberton placed his first ad (in the Atlanta Journal) for the drink. It began as a cure for his morphine addiction, and, sadly, he sold the rights for a pittance shortly before he died at 57.  On this day in 1913, Stravinsky’s ballet score The Rite of Spring was first performed in Paris, provoking riots. Now, of course, it’s well loved classical music.  On this day in 1919, Arthur Eddington and Andrew Claude de la Cherois Crommelin tested Einstein’s theory of general relativity, leading to its confirmation, although I heard this test wasn’t as good as people claim.  For all mountaineers it’s a banner day, for it was on May 29, 1953, that Edmund Hillary and Tenzing Norgay became the first people to climb Mount Everest. Finally, on May 29, 1990, Boris Yeltsin was elected president of the Russian Soviet Federative Socialist Republic by the Russian parliament.

Notables born on this day include Patrick Henry (1736), G. K. Chesterton (1874), Oswald Spengler (1880), Bob Hope (1903), Tenzing Norgay (summited on his birthday!, born 1914), John F. Kennedy (1917), Peter “Boson” Higgs (1929), Paul R. Ehrlich (1932), mountaineer Doug Scott (1941), John Hinkley, Jr. (1955), Annette Bening (1958) and Melissa Etheridge (1961). Those who died on this day include Humphry Davy (1829), W. S. Gilbert (1911), John Barrymore (1942), Moe Berg (1972), Barry Goldwater (1998), Archibald Cox (2004), Dennis Hopper (2010), Doc Watson (2012), Walter Gehring (2014), and Manuel Noriega (last year).

Meanwhile in Dobrzyn, Hili, for once, isn’t kvetching! And she’s very cute in the cherry tree.

Hili: There are such moments.
A: What moments?
Hili: When I lack any reasons to complain.
In Polish:
Hili: Są takie chwile.
Ja: Jakie?
Hili: Kiedy brakuje mi powodów do narzekania.
In Winnipeg, Gus is walking proudly on his leash:

Some tweets from Matthew. First, an amazingly cryptic katydid (watch the video):

I wish I had been this guy who was reading. What a treat!

I graduated in 1971, when facial hair was at its peak:

What I want to know is how they could tell males from females in macaws. I thought they were morphologically identical.

You all know this story about an immigrant from Mali to France who climbed four floors outside a building to rescue a dangling child. Watch the video:

Who he is:

He was granted French citizenship after saving the child (story here): a fitting tribute.

And a couple of humorous/sarcastic remarks about the situation:

Monday duckling report

May 28, 2018 • 2:30 pm

So far so good: still eight ducklings. They all look good and seem quite vigorous. The family sleeps on the tree island at night; here they are in the a.m., with Honey not fully awake.

They’re eating well, too, now taking avidly to Cheerio crumbs, but still rejecting veggies. Honey is getting a decent amount of corn, but I await the arrival of my duck pellets this week.  As for Sir Francis, he keeps a decent distance from the others, and I throw him food now and then to keep him from encroaching. He’s also learned to avoid the sight of my fly net, which I brandish to stop his forays toward the family (I never hit him or touch him with it; it’s just a banner that I wave and shout, “Frank–NO!”)

Here’s the brood:

After meals, they all repair to the tree island, and Honey grooms herself. I think the ducklings emulate her and groom as well; it’s very cute.  Also, I saw the first dabble by a duckling today, who went bottoms up after a sinking piece of corn (successfully).

Here they’re all grooming:

Trump’s Memorial Day tweet: It’s all about him

May 28, 2018 • 1:00 pm

Crikey, what a self-aggrandizing tweet from the U.S. “President”! It’s all about him.  He has not an ounce of empathy in him, and these are simply empty words for public consumption.

Jebus.

Seriously, people died for our great country so Trump could fix it? Gag me with a spoon.

Josh Dehaas on “Indigenous ways of knowing” (aka “faith”)

May 28, 2018 • 12:00 pm

Quillette remains a good source of liberal but critical articles, refreshingly free of clickbait and ever critical of Control-Leftism. One recent article worth reading is by Josh Dehaas, “‘Indigenous Ways of Knowing’: Magical Thinking ahd Spirituality by Any One Name.” Dehaas, described as “a Toronto based freelance journalist”, is critical of a Canadian government initiative to put “indigenous ways of knowing” alongside “Western” ways of knowing as equally valid methods for understanding nature. It turns out that while some of these “indigenous ways of knowing” may have a valid core, in the main they’re based on revelation, guesses, and tradition—forms of faith. In no way are they, taken together, comparable to the empirical approach used by scientists and science-based researchers, engineers, or even car mechanics—a method I called “science construed broadly” in Faith Versus Fact.

First, the issue. There’s no doubt that Canada treated its indigenous people horribly. Many children were ripped from their parents, sent to schools where they were forbidden to speak their own language or practice traditional customs—an attempt to forcibly turn them into European Canadians. The country has rightfully tried to make reparations for this and similar forms of ill-treatment, and that’s to be applauded.

But in one way these reparations have gone too far. By attempting to teach indigenous “ways of knowing” as valid, the Canadian government and its universities are putting truly valid ways of understanding nature alongside ways that are not rigorously tested, and indeed, can be dangerous.

Now you’ve heard this equivalence of knowledge in at least two other areas: religion, which also claims “ways of knowing” based on revelation, dogma, authority, and simple faith, and postmodernism, which in some forms holds that there are many “ways of knowing”, with science just one among many, and not privileged in any way.

But we also have the indigenous ways of knowing held by what Canadians call “First Nation” people. Dehaas outlines how these ways are being validated:

From the University of Calgary to The University of Saskatchewan to Acadia University in New Brunswick, Canadian deans are pledging to infuse their curricula with a doctrine often described as “Indigenous Ways of Knowing” (IWK), which teaches that Indigenous peoples arrive at their understanding of the world in a unique way.

The idea has been around in some form for many years. In a research paper prepared for the Canadian government in 2002, for instance, Indigenous education scholar Marie Battiste argued that Indigenous peoples possess a “cognitive system” that is “alien” to Europeans. But in recent years, the concept has gained critical mass, as education officials seek to incorporate IWK into university coursework. Much of the impetus has come from the publication of the Final Report of Canada’s Truth and Reconciliation Commission (TRC) in 2015.

The TRC was created as part of an attempt to formally recognize and heal the damage done by the Indian Residential School System, which for generations served to separate Indigenous children from their parents, thereby stripping them of their culture, often under abusive conditions. One of the TRC’s many recommendations was that Canada’s educational institutions treat “Aboriginal and Euro-Canadian knowledge systems with equal respect.” This prompted the universities’ main lobby group, Universities Canada, to exhort members to ensure “mutual respect for different ways of knowing,” and encourage “the cohabitation of Western science and Indigenous knowledge.”

Formally recognizing the harm done by the residential school system is a laudable goal. But I have yet to see any evidence that scholars create knowledge in fundamentally different ways, based on their ethnicities, as IWK proponents claim.

One example:

In an introductory IWK lecture, Paul Restoule, a professor at the University of Toronto’s Ontario Institute for Studies in Education (OISE), starts off by telling his class that “knowledges” are subjective. He also claims that the mere act of defining IWK is “problematic,” since any definitions would use “Western knowledge” as a frame of reference. This is not unusual. I’ve been writing about higher education for a decade, and have investigated the issue of IWK on different campuses. Invariably, my attempts to determine the exact parameters of IWK always meet with this somewhat gauzy, defensive response. Oddly, the most zealous proponents of IWK also are the ones who are the most reluctant to describe what it is.

Restoule claims that, for Indigenous people, “the senses can know more deeply and concretely than knowledge gained through reading and being told.” He asserts that “knowledge is sometimes revealed through dreams, visions and intuitions.” And he offers a Venn diagram with a circle for “Western science”—“limited to evidence and explanation within [the] physical world” and “skepticism,”—overlapping somewhat with a circle for “Indigenous knowledge,” which is described as “holistic,” involving a “metaphysical world linked to moral code” and “trust for inherited wisdom.”

That’s not knowledge, but faith that’s equivalent to religious faith!

Now I don’t know how pervasive this kind of nonsense is, but we know that First Nations people have been allowed to impose on their dying children “native medicine” rather than Western science-based medicine, with the predictable results: the kids die.(Sometimes the courts support this travesty.) I’ll count on Canadian readers to inform me if Restoule’s attitude is an outlier. I suspect it isn’t.  It is instead, as Dehaas observes, “a combination of magical thinking and spirituality.”

He adds:

Whenever proponents are asked to define IWK, “at some point in the conversation, postmodern relativism begins to enter into it,” she says. When asked to explain the unique “ways of knowing” exhibited by Indigenous peoples, advocates tend to describe either folk knowledge or spiritual beliefs, she adds. These may indeed be described as “alternative” ways of knowing. But their alternative character originates in the fact that they present themselves as exempt from the expectation of rigorous scrutiny that typically is applied to claims made by academics.

And it’s that absence of rigorous scrutiny and empirical testing that makes these “alternative ways of knowing” so dangerous.

Now some of you may be thinking, “But many modern medicines are derived from traditional plant-based remedies.” And indeed, that’s true: quinine as a remedy for malaria is the quintessential example. But the evidence that led to these plants being efficacious was still anecdotal: they seemed  to work. Now in the case of quinine they actually did work, but to find out rigorously if they work, you have to do proper empirical testing, using blind tests and statistics. That’s why all plant-based medicines, whether derived from local cultures or not, must be vetted by proper scientific testing.

After all, there are plenty of “traditional” remedies that don’t work at all: have a look at the Canadian Cancer Society’s page on “Aboriginal traditional healing“, which outlines many First Nations methods for cures that aren’t efficacious, including smudging, healing circles, and herbal medicines (some of which have been used on children with cancer). To its credit, the Society notes that there’s no evidence that any of these methods can be used to treat cancer, but the point is that people have used them—because they’re derived from “indigenous ways of knowing.”

Ditto for spiritual healing. That, like religion, is also an indigenous “way of knowing”, and may have some placebo effects, but if you had an infection, would you opt for smudging (inhaling the smoke from burning sacred herbs)— or antibiotics? By all means, if indigenous “remedies” aren’t harmful, make the patient feel more comfortable, and help him to take scientific medicine, use the other stuff as well. But don’t pretend that it’s a cure based on “other ways of knowing.”

Of course people who have been trod upon need their oppression remedied, and the Canadian government has taken admirable steps in that direction. But validating “indigenous ways of knowing”, at least insofar as they are claimed to produce truth about nature and the cosmos, isn’t one of them. There is only one valid way of knowing: a rigorous empirical method designed to overcome confirmation bias, and undergoes tests and replication. It’s called “science”.

The erosion of free speech in Britain: blogger and YouTuber convicted of anti-Semitism and Holocaust denialism

May 28, 2018 • 10:30 am

An anti-Semitic British woman has just been convicted, and may well be jailed, for posting “grossly offensive” songs on YouTube. This is just another step in the continuing erosion of free speech in Britain. In effect, what she was convicted for was anti-Semitic statements (not illegal in the U.S.), which include denying the Holocaust. She also claimed, in her songs, that Auschwitz was a “theme park.”

As both the BBC and the Guardian report, Alison Chabloz of Derbyshire wrote and performed several anti-Semitic songs in public and posted them as well on her Youtube channel (the site is here, but the offending material seems to have been removed).

From the Guardian:

Alison Chabloz, 54, was convicted of three charges relating to three of her songs at Westminster magistrates court on Friday. The district judge, John Zani, said he was satisfied the material was grossly offensive and that Chabloz intended to insult Jewish people.

The prosecutor Karen Robinson previously told the court: “Miss Chabloz’s songs are a million miles away from an attempt to provide an academic critique of the Holocaust. 

The songs Chabloz were charged over included one titled (((survivors))) – using the white supremacist online convention of placing Jewish names within three brackets. The prosecution was initially brought privately by the charity Campaign Against Antisemitism, then taken over by the CPS.

. . . About 20 supporters of the musician groaned when the verdict was given, with shouts of “shame” from the public gallery.

Chabloz had uploaded the songs to YouTube, as well as performing them at a London Forum event in 2016. They included one song describing the Nazi death camp Auschwitz as “a theme park” and the gas chambers a “proven hoax”. The songs were in part set to traditional Jewish folk music.

Adrian Davies, defending, previously told Zani his ruling would be a landmark one, setting a precedent on the exercise of free speech. He had argued his client did not commit an offence, saying: “It is hard to know what right has been infringed by Miss Chabloz’s singing.”

From the BBC:

Chabloz, who describes herself as a Holocaust revisionist, said her music was “satire” and had previously told the court there was “no proof” gas chambers were used to kill Jewish people in World War Two.

However, prosecutors said three of Chabloz’s songs, including one which referred to the notorious Nazi death camp Auschwitz as a “theme park”, were criminally offensive.

Another song included a section set to the tune of a popular Jewish song Hava Nagila.

Indeed, what right was infringed by Chabloz’s songs? Is “insulting Jewish people” a crime? Not in my book. It’s reprehensible, and brands you as a slimeball, but it’s not a crime.

Don’t get me wrong: although Chabloz claims her songs were satirical and that some Jews found them “funny” (I doubt that!), there’s little doubt she’s a Jew-hater. Is that illegal? And is it illegal to deny the Holocaust, even if it’s not an “academic critique”? Remember, Jew-hating elides into Muslim-hating, which elides into criticism of Islam, which elides into all kinds of “offensive” speech whose prohibition, as John Stuart Mill so eloquently argued, is inimical to the public good. That includes, these days, questioning affirmative action, the tactics of Black Lives Matter, and whether unequal representation of the sexes in jobs is prima facie evidence of sexism.

Even denying the Holocaust, however “academic” your arguments may be, is useful: it not only outs a person’s views, but gives us an opportunity to study the issue and rebut the claims. As I’ve said before, it was Holocaust denialism that got me to read the rebuttals of these cranks by historians, and that in turn has not only educated me, but also made me a better critic of this form of bigotry. Without the knowledge gained in an attempt at refutation, all you can do is sputter and call the other side names.

Here’s one of Chabloz’s milder songs; you’ll have to go to YouTube to hear it and also click on a box saying that you accept that it’s identified as “inappropriate and offensive” but you want to watch it anyway. At 24 seconds in, she makes the “quenelle“, an anti-Semitic gesture—a stylized Nazi salute—popularized by the bigoted French entertainer Dieudonné M’bala M’bala. The song, based on a famous (and innocuous) Edith Piaf recording, attacks Zionists and expresses Chabloz’s lack of regret for her attacks on Jews.  This, apparently, is a milder version of the songs for which she was convicted.

But she’s right: a song’s not a crime, even a bigoted one.

The increasing suppression of speech in the UK (and Canada) disturbs me. Will it snuff out bigotry? No, it will just drive it underground and allow bigots to play the censorship card, even gaining adherents. Is the UK better off than the U.S. because of such prosecutions? I don’t see how.

So let the bigots speak. Bring on the anti-Semites. Let them call me a Jew, a sheenie, a Hebe, a Christ-killer, a big nosed, money-grubbing kike! Let them say that the Jews should have been exterminated. I will fight them (verbally), but I’ll also feel sorry for them, for they’ve outed themselves as reprehensible, shameless haters. And they’ll get no traction in today’s society for, as Steve Pinker argues, our morality has progressed. Britain is going down a very dangerous road with prosecutions like this.

Chabloz was supposed to be sentenced last Friday, but I can find no record of what happened.

I get comments

May 28, 2018 • 9:15 am

Here’s a comment from one “Dominick” that arrived in the moderation box. I’m posting it here largely because Dominick claims to be a “mental health professional.” Tracing his email address, which of course I won’t divulge, I found that this is true. Do we really want people like this helping others become mentally healthy?

The comment was intended for my post: “Moving Naturalism Forward videos now online“. I reproduce it exactly as posted.

Free Will exist as does God. If mankind was living in an atopia we couldn’t handle it. The current state of affairs leaves one to question God while it is clear to me that our though and decisions are our own to be later scrutined by the man upstairs. Why? Because the human condition was created by a choice that was influenced by evil. As a mental health professional I see evil and mental health as a difference. Whether one buys into the Bible and it’s events or not there is a supreme being and a evil force at work. The human condition is a struggle and there is reasoning even in tragedy. Human reasoning can be likened by Thomas Aquinas but even above reasoning rains valid if it we’re known. I live in the mystery myself with faith hope and love. Just my humble opinion I don’t sell it. I respect others views.

“Just my humble opinion I don’t sell it.” I think there are two lies there. . .

Kudos to any reader who can figure out what this guy is saying.
